Answer:
X+y=30
X=30-y
Z=yx
Z=y(30-y)
D/dy
z=30–2y
At max 30–2y=0
2y=30 Y=15
Therefore x=15
Step-by-step explanation:
Answer:
x=12
10x = 120
5x = 60
Step-by-step explanation:
paralellograms will become 360 degrees
so 2(5x) +2(10x)= 360
Simplify:
10x + 20x = 360
= 30x
divide both sides by 30 and isolate
<u>30x </u> = <u>360</u>
30 30
x=12
multiply 12 by 10x and 5x
10x = 120
5x = 60
Answer:
B
